I'm going to go ahead and move this to the correct section (AMD Motherboards).

EDIT: I guess I can be helpful too

Phases of a motherboard and phase change (cooling) are two different things. Phases on your motherboard regulate power to the processor. Insufficient or overloaded phases can often "burn up" or literally melt from too much amperage going through them.

Phase change is a type of cooling which makes use of standard refrigeration system (compression, evaporator, condenser, etc.) which is designed to give temperatures in the magnitude of -10Â°C all the way down to -180Â°C depending on how many "stages" you have.
